Key Features and Benefits
The CAN Scan D900 boasts a comprehensive suite of features that make it a standout OBD2 scanner in its price range:
Broad OBD II / EOBD Protocol Support
This scanner supports all prevalent OBD II and EOBD protocols, ensuring wide vehicle compatibility:
- CAN (Controller Area Network): The modern standard for vehicle communication.
- KWP 2000 (ISO 14230-4): Common in European and Asian vehicles.
- ISO 9141-2: An older standard still found in some vehicles.
- SAE J1850 PWM & SAE J1850 VPW: Protocols used by many Ford and GM vehicles.
This extensive protocol coverage means the D900 CANScan OBD2 scanner is likely to be compatible with a vast majority of vehicles manufactured from 1996 onwards (in the USA) and 2001 onwards (in Europe). It supports a wide array of car brands, including Audi, BMW, Ford, Honda, Hyundai, Kia, Lexus, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Suzuki, Toyota, Volkswagen, and Volvo, among others.
Comprehensive Diagnostic Functions
The D900 CANScan OBD2 scanner provides a range of diagnostic capabilities:
- Real-time Data Stream: Monitor live OBD II / EOBD data, including sensor readings and calculated engine parameters. This allows you to observe your engine’s performance in real-time.
- Read and Erase Diagnostic Trouble Codes (DTCs): Identify the source of the “Check Engine Light” by reading both standard and some manufacturer-specific fault codes. The scanner also enables you to clear these codes after repairs, turning off the warning light.
- Freeze Frame Data: Capture and review the data snapshot recorded at the moment a fault code is triggered. This “freeze frame” information is crucial for diagnosing intermittent issues.
- Check Engine Light Status: Quickly determine if the Malfunction Indicator Lamp (MIL) is on or off.
- I/M Readiness Status: Verify the readiness of your vehicle’s emission control systems for smog testing.
- Vehicle Information: Retrieve important vehicle data such as VIN (Vehicle Identification Number).
- Last Scan Memory: The device automatically saves the results of the last scan, storing up to 30 fault codes for later review. This is helpful for tracking intermittent problems or reviewing past diagnoses.
User-Friendly Design and Features
The D900 CANScan OBD2 scanner is designed for ease of use:
- Large, Clear Display: A 3-inch screen with 128×96 resolution and 8 lines of text, featuring adjustable backlight brightness, ensures easy readability in various lighting conditions.
- Built-in Help System: Access descriptions of sensors, fault codes, and other helpful information directly on the scanner, reducing the need to constantly consult external resources.
- Compact and Portable: Its dimensions (20x9x3 cm) and light weight (200g) make it easy to handle and store.
- Protective Case: A convenient zippered case with compartments for the cable and a handle is included for safe storage and portability.
